Why is my ex messing with my head?

Anonymous
He keeps pining over me, wanting my attention and stalking my online activity. He's befriending and hanging with MY friends and trying to "accidentally" run into me. When I see him, he keeps staring at me like there was nothing else in the world. But we don't really talk, call or message each other. He comes online every time I'm online, but doesn't say a word. If I give him attention and care about his life, he backs off. And when I take some distance he won't let me go. The break up was pretty bad and I could see him suffer (he suggested it, I just said OK). He tried to get my affection while we were not talking and when it got to a point where I was genuinely worried about him I took contact and we cleared the air. After that we've been distant but fine. Except he keeps wanting me to notice him BUT at the same time he's flaunting how he has a "new girl" now in social media (might as well not). So what is he doing and why? I just want us to be cool (friends or relationship) or have nothing to do at all. This is all just too much.

SHORT: Bad break-up, made peace with ex, ex tries to get my attention and "accidentally" run into me + befriends and hangs out with my friends, won't let me go but flaunts his "new gf" in social media. Why is he doing this?
